Pressure Gauge Plunger for Platforms for Extrusion-Based 3D Printing of Semisolid Masses

Abstract

The pressure gauge plunger for 3D printing platforms is applicable in various 3D printing fields (bioprinting of tissues; and the food, pharmaceutical, and ceramic industries). Its usefulness is rooted in its ability to continuously control the pressure applied during the entire printing process, thanks to the plunger mechanism. It thereby allows improved quality and detection of errors in situ, allowing corrective actions to be applied during the process. The pressure value that the printing platform component exercises on the plunger (and, thus, on the mass to be extruded) is obtained through use of a stress gauge, This continuous control allows profiling of the printed semi-solid mass, permitting the most appropriate printing parameters to be set in situ, further allowing the process to become completely automated.
